Answer:

129

Step-by-step explanation:

Use PEMDAS.

Parenthesis: (Multiply, then divide) 3*2=6, 12/6=2

Exponents:8^2=64

Multiply: 9*2=18

(No subtraction here!)

Add: 82+18

=129

Answer:

129

Step-by-step explanation:

The order of operations is PEMDAS

P = parenthesis

E = exponents

M = multiplication

D = division

A = addition

s = subtraction

starting with

$8^{2}$ + 9 (12 / 3 x 2) - 7

We first work the terms in the parenthesis ( 12 / 3 x 2)

A rule is if all the operations are multiplication and division only we work from left to right so (4 x 2) then (8)

$8^{2}$ + 9(8) - 7

Next we take care of the exponent (the remaining parenthesis are a multiplication operation not parenthesis that contain other operations)

64 + 9(8) - 7

Next we do the multiplication

64 + 72 - 7

Another rule is if all the operations are addition and subtraction we work from left to right

136 - 7

The Asian elephant is an endangered species with a current population of 45,000. This species is said to be experinceing a decli

hram777 [196]

Answer:

5 years

Step-by-step explanation:

Given that

The current population is 45,000

The rate of interest in declining would be 4.5% per year

The expected population is 35,746

We need to find out the no of years

Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955

Now

Year 1 = 45,000 × 0.955 = 42,975

Year 2 = 42,975 × 0.955 = 41,041.125

Year 3 = 41,041.125 × 0.955 = 39,194.27

Year 4 = 39,194.27 × 0.955 = 37,430.53

Year 5 = 37,430.53 × 0.955 = 35,746.16

Hence, the no of years would be 5

In 2016 there were about 64,500 cinema screens in a country. If about 29.9% of screens in the country were digital 3-D screens,

zhenek [66]

Answer:

Step-by-step explanation:

In 2016 there were about 64,500 cinema screens in a country.

If about 29.9% of screens in the country were digital 3-D screens, we would determine the approximate number of 3D screens by dividing the Percentage of 3D screens by the total percentage of 100 and multiplying by the total number of cinema screens. It becomes

29.9/ 100 × 64500 = 0.299 × 64500

= 19285.5

The number of 3D screens is approximately 19286
